TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 444,695, dated January13, 1891.

Application filed March 10, 1890. Serial No. 343,347. (No model.)

To all whom it may concern:

Be it known that I, JACOB DORNBIRER, a citizen of the United States,residing at Sandusky, in the county of Erie and State of Ohio, haveinvented certain new and useful Improvements in Temporary Binders, ofwhich the following is a specification, refererence being had therein tothe accompanying drawings.

This invention relates to new and useful improvements in temporarybinders; and the invent-ion consists in the peculiar construction andarrangement of parts, as more fully hereinafter described and claimed.

In the drawings which accompany this specification, Figure 1 is aperspective view of the parts. Fig. 2 is a plan view; Fig. 3, ahorizontal section through Fig. 2, showing locking-bar in its openposition; and Fig. a is a similar view with the bar in its lockedposition. Fig. 5 is adetached perspective view of one of thebinding-thorns. v

A is a stiff cover, preferably made of sheet metal, having one edge bentto form the back B and flange G.

D are removable binding-thorns, which are preferably made, as shown inthe drawings, of a piece of wire sharpened at one end, having a verticalportion a, foot b, and shank c.

E are sockets soldered or otherwise secured to the cover A and adaptedto receive the shank of the thorns D and hold said thorns in position byfrictional engagement.

F is a locking-bar hinged at one edge to the flange G and adapted tofold over the same. This bar is provided with the flange G, havingsuitable apertures f, corresponding in numher to the thorns D, andinwhich said thorns are adapted to be engaged in the elosedposition of thebar.

II is a gage-plate, preferably made of sheet metal, having notches g onone edge and suitable spring hooks h, adapted to engage over the back Bin the operation of the device, as more fully hereinafter described.

J are cars secured at one edge to the cover A, on which a suitableamount of binding cord K may be wound.

In practice the parts operate as follows: The locking-bar being in itsopen position, as shown in Figs. 1, 2, and 3, the operator first placesthe. gage-plate H within the fold of the paper he wishes to place in thefile, thus engaging the hooks h over the back B. He next turns down thelocking-bar. It will be seen that in this position the fold or bindingedge is kept in close contactwith the back 13, and as the notches 9correspond in number and position to the thorns D the latter are free toperforate the paper when the bar is closed down upon them. IVhen a poorquality of paper is used, instead of depending upon the thorns D for thesecuring of the pa per, it may be found desirable to use in addition thebinding-cord, a suitable quantity of which is always at hand on the earsJ. This cord may be placed in the fold with the plate II and afterwardwound around the back 13. \Vhenever it is desired to remove the papersfrom the file, as at the end of a year, it may be done by simply openingthe bar F, after which the thorns are free to be disengaged from theirsockets E by sliding the bound numbers from the cover. In so doing thethorns are left sticking in the perforations in the papers and may beremoved one at a time and a binding-cord substituted. \Vhere the cord Khas been used, it will be necessary to cut it across the back before thepapers can be removed; but the ends may then be knotted or secured tothe cords substituted for the thorns, thus giving additional strength tothe permanent binding. lVhen the gage-plate is not in use, 1t may beplaced beneath the papers next to the cover and secured in that positionby the hooks it.

Another advantage of the flange 0 is to form a convenient hand-hold forthe reader while using the file.

hat I claim as my invention is 1. The combination with the coverprovided with the thorns and back of the cover, of the gage-plate havingnotches corresponding with the thorns, and hooks secured to saidgageplate and adapted to engage with the back of the cover,substantially as described.

2. The combination, with the cover provided with the thorns and the backof the cover, of the gage-plate adapted to engage in the folds of thepaper and made of a size to project beyond the upper and lower edge ofthe paper, the spring-hook secu red to said projecting edges, and theflaring notches formed on the inner edge of said gage-plate andcorresponding with the thorns, substantially as described.

In a temporary binder, the combination, with the cover and a back formedintegral therewith, having an outward-projecting flange forming ahand-hold, of thorns detachably secured in proximity to said back andhaving shanks parallel therewith, substantially described.

4. In a temporary binder, the combination of the cover A, back B, theoutwardly-projecting flange integrally'formed therewith, the locking-barhinged to said flange and provided with apertures f, and the thorns D,secured to the cover, substantially as described.

5. The combination, with a cover, of the thorns provided with theupright portions, the foot formed thereon, and the shank slidinglyengaging into sockets E, formed on the cover, substantially asdescribed.

6. In a temporarybinder, the combination of the cover A, back B andoutwardly-projecting flange (J integrally formedtherewith, a locking-barhinged to said flange and provided with the apertures f, and the thornsD, secured to the cover, and gage-plates H, provided with spring-hooks hand flaring notches g, all arranged to operate substantially asdescribed.

7. The combination, with the cover A, provided with the back B, ofthorns detachably secured in sockets to said cover a short distance fromsaid back, said thorns having a vertical portion a, foot I), and shank0, adapted to be engaged in said sockets, substantially as described.

In testimony whereof I affix my signature, in presence of two Witnesses,this 10th day of February, 1890.

JACOB DORNBIRER.
